About Us

The experience of the Mencarelli family in the mechanical field began early in the last century, in 1925. At the time of its foundation in 1969, Torninova’s experience had already developed, leading the company to specialize in technical support for extrusion lines.

Later, in 1993, Torninova started designing and manufacturing air bubble film machines, stretch film machines and dimpled drainage membrane machines.

The company has always been highly involved in research and development in order to offer its customers versatile and flexible systems that combine the most innovative electronic and mechanical technologies.

A commitment to meeting the highest possible standards has led the Torninova Corporation to design its complete range of stretch film machines, air bubble film machines and dimpled drainage membrane machines, and to acquire top know-how in the field, now available to its customers.

Torninova Corporation brings to the market the very best in stretch film production technology thanks to its thorough research and development in collaboration with Italian and American University professors, renowned European manufacturers of extruder components and experienced figures from the field of extruded stretch film. Our Client partners (both Italian and foreign) also support our research and development phases by purchasing prototype systems to scientifically test and continuously monitor each single component and process. During such tests, appropriate adjustments are made in response to real time controlsunder actual production conditions. The result is a perfectly integrated system of cutting edge components, calibrated and arranged into a compact, high-performance cast line that provides maximum flexibility with minimum energy consumption.

Here are some hallmark components of the COMPACT STRETCH system:

The LLPOWEREX extruder series features special screw profiles, AC motors and infrared heaters ensuring limited maintenance and low energy consumption, that have been specifically developed to guarantee perfect LLDPE extrusion. The SWIFTCOOL chill-roll unit’s dual cooling rollers guarantee total material stabilisation. A dual-chamber vacuum box with automatic die adjustment and an integrated

x-ray device to measure material thickness (guaranteeing accuracy even with coloured stretch film) offers the finest and fastest control features for the film extrusion process.

Customers can choose from three different winding systems:

Our exclusive non-stop NGW-6S Patented winder for hand, machine and jumbo rolls allows switching from rolls on 2-inch cores to 3-inch cores (and vice-versa) without ever stopping the line or reducing the production speed. This winder allows producing coloured stretch film just as easily. The cycle time is 18 seconds and the thickness range is 7-50 µm. There will be no need to waste time for line stops and shaft changing. This winder lowers the energy consumption, requires less operators and no production and storage scheduling are needed.

The fast and reliable QUICKSILVER-4S winder (rewind cycle time of 16 seconds) directly rewinds stretch film into rolls on 2-inch or 3-inch cores (suitable for hand and machine use), in formats ranging from 100 mm to 250 mm, 450 mm and 500 mm.

The QUICKGOLD-4S is Torninova’s patented, universal, all-in-one evolution of hand and machine roll winders. Maintaining the same characteristics, it can also produce jumbo rolls up to a maximum diameter of 420 mm.

The winding cycle still remains extremely fast (around 18 seconds) without compromising the production of hand rolls, even at very high speed. Optional roll handling features can be integrated into each winder to assure steady, high-speed cast stretch film production. For instance, the automated packaging system packs hand rolls in a 6-unit cardboard box.

Another component which sets the machine apart from others is the FULLFEED trimming system with a force-feed device specifically designed for the type and quantity of trimming required by a stretch film machine. A suction device completely recovers all chopped trimmings for re-use by the main extruder line, thus preventing variations in pressure and film thickness even in the event of frequent changes in production and operating speed.

The FULLFEED system eliminates potential non-uniformities in film thickness, including those in longitudinal sections.

Upon request, instead of the flake re-feeding system, it is possible to equip the COMPACT STRETCH with a recycling machine that completely re-granulates edge and bleed trims.

PERFECTLY INTEGRATED, HIGHLY FLEXIBLE SYSTEM

The new COMPACT STRETCH series is not a simple combination of standard components from various processes but, on the contrary, is a well-developed, well-tested, made-to-measure integrated system guaranteeing maximum simplicity and flexibility in the production of high-quality rolls of co-extruded cast stretch film.

INTEGRATEDSOLUTIONS

Everyday, producers of stretch film have to face the rise in the cost of raw materials, labour and energy. Producers thus find themselves in an increasingly competitive market in which profits are constantly driven down.

In these circumstances, profitable production is only attainable with a system that guarantees elevated and continuous production, 24 hours a day. Torninova Corp. has focused all of its attention on this aspect, developing and designing affordable systems for high-output production. The result has been an increase in sales and satisfied Clients in a very competitive market.

FAST AND RELIABLESOLUTIONS

All machines are equipped with a PLC-managed control system which runs touch-screen operated supervisory software for programming and managing the entire system.

The operator can use customized formulas to manage production according to the required percentage of co-extrusion and the needed production speed.

The machine can be remotely diagnosed via Internet to provide immediate customer assistance.

IN-LINE EDGE FOLDING SYSTEM

TECHNICAL DATA

• Folded area width: 2-3 mm• Film thickness: any thickness

in the produced range

This direct ink-jet printing unit allows you to further customize your product as well as make it interactive and traceable by applying logos, names and much more on your film. The printing options are unlimited and the print can vary with each production change. The film thickness and performances will have no variation whatsoever. The process is fast, clean and does not require any additional operators or special maintenance. When placed on your stretch film line, the printing unit will be managed through an integrated software and remote control which allows to easily set job parameters and facilitates problem-solving. Ordinary maintenance operations are facilitated by the printhead extraction system. The printing and film production speed are synchronized and the printing units are automatically interrupted if the line stops.

This system, patented by AKRO FLEX, was designed to be placed in-line on your stretch film machine and it does not require any additional off-line processing on the film. It allows producing stretch film with double, reinforced edges which increase the load holding force and tear resistance of the film. Thus, the performances will be higher than those of a standard material. By making a lower thickness material, the producer will achieve the same high wrapping performances of a thicker material. This also means reducing the amount of plastic film and protecting the environment. The edge-folding system is also equipped with a trims suction unit when operating. The edge-folder’s positioning on the winding unit can be studied and planned upon request.
